oVirt hook to manage physical CPU pool, and automatically pin CPUs without overlap on the host
by David Jorm 02 Feb '16

02 Feb '16

Hi All Thanks for the help that people have recently provided on this list. I'm running into another edge case that, as far as I can see, does not have a native solution within oVirt. I have a use case where every VM must have 4 pinned vCPUs, and these must map 1:1 to physical CPUs so that there are never two VMs contending for the same physical cores. I already have code in place that ensures a VM will not be created or started if n/4 VMs are already running on the target host, where n is the number of physical cores. What I need now is to ensure that pinning is managed so that each physical core maps 1:1 to vCPUs. Would it be possible to manage the pool of physical cores in a local DB, and implement a VDSM hook similar to the example on this page? http://www.ovirt.org/VDSM-Hooks Or would there be a preferable solution? Thanks David

Storage network clarification
by Fil Di Noto 02 Feb '16

02 Feb '16

I'm having trouble setting up a dedicated storage network. I have a separate VLAN designated for storage, and configured separate IP addresses for each host that correspond to that subnet. I have tested this subnet extensively and it is working as expected. Prior to adding the hosts, I configured a storage network and configured the cluster to use that network for storage and not the ovirtmgmt network. I was hopping that this would be recognized when the hosts were added but it was not. I had to actually reconfigure the storage VLAN interface via oVirt "manage host networks" just to bring the host networks into compliance. The IP is configured directly on the bond0.<vlanid>, not on a bridge interface which I assume is correct since it is not a "VM" network. In this setup I was not able to activate any of the hosts due to VDSM gluster errors, I think it was because VDSM was trying to use the hostname/IP of the ovirtmgmt network. I manually set up the peers using "gluster peer probe" and I was able to activate the hosts but they were not using the storage network (tcpdump). I also tried adding DNS records for the storage network interfaces using different hostnames but gluster seemed to still consider the ovirtmgmt interface as the primary. With the hosts active, I couldn't create/activate any volumes until I changed the cluster network settings to use the ovirtmgmt network for storage. I ended up abandoning the dedicated storage subnet for the time being and I'm starting to wonder if running virtualization and gluster on the same hosts is intended to work this way. Assuming that it should work, what is the correct way to configure it? I can't find any docs that go in detail about storage networks. Is reverse DNS a factor? If I had a better understanding of what oVirt is expecting to see that would be helpful.

memory leak in 3.5.6 - not vdsm
by Charles Kozler 01 Feb '16

01 Feb '16

Here is a screenshot of my three nodes and their increased memory usage over 30 days. Note that node #2 had 1 single VM that had 4GB of RAM assigned to it. I had since shut it down and saw no memory reclamation occur. Further, I flushed page caches and inodes and ran 'sync'. I tried everything but nothing brought the memory usage down. vdsm was low too (couple hundred MB) and there was no qemu-kvm process running so I'm at a loss http://imgur.com/a/aFPcK Please advise on what I can do to debug this. Note I have restarted node 2 (which is why you see the drop) to see if it raises in memory use over tim even with no VM's running [compute[root@node2 log]$ rpm -qa | grep -i ovirt libgovirt-0.3.2-1.el6.x86_64 ovirt-release35-006-1.noarch ovirt-hosted-engine-ha-1.2.8-1.el6.noarch ovirt-hosted-engine-setup-1.2.6.1-1.el6.noarch ovirt-engine-sdk-python-3.5.6.0-1.el6.noarch ovirt-host-deploy-1.3.2-1.el6.noarch -- *Charles Kozler* *Vice President, IT Operations* FIX Flyer, LLC 225 Broadway | Suite 1600 | New York, NY 10007 1-888-349-3593 http://www.fixflyer.com <http://fixflyer.com> NOTICE TO RECIPIENT: THIS E-MAIL IS MEANT ONLY FOR THE INTENDED RECIPIENT(S) OF THE TRANSMISSION, AND CONTAINS CONFIDENTIAL INFORMATION WHICH IS PROPRIETARY TO FIX FLYER LLC.

[FC22] testing oVirt 3.6.2 : Hot plug memory not working
by wodel youchi 01 Feb '16

01 Feb '16

Hi, I am using oVirt 3.6.2 on FC22 box, all-in-one installation, my purpose is to test it. I am using a simple Desktop : - one cpu core i5 3550 with 4 cores - 2x4 Go of RAM I installed a Centos 6x64 VM with all updates + ovirt guest agent. I tried to augment the memory from 1024 to 1536 (+512Mo) it didn't work I had to shutdown the VM for the change to take effect. Hot plug memory does it have something to do with the underneath hardware? or does it depend on the guest OS? or something else? Regards.
